Fitted a boost gauge today , I bought a spare steering cowl incase I meseed up or i decided I didn't want it anymore , also fitted a switch for the light on the gauge as at night it could be a pain being bright white 335d boost gauge:

Sort of boost pressure you seeing and are you standard ?

That boost gauge doesn't read high enough for my 335d now it's mapped haha!

It'll be 32 ish psi

not driven it yet,only use it at the weekend and this weekend is the last one i will use it this yr,soon as i go out i will find out,just been finishing it today and pressure testing it,mine is dpf deleted and remapped,the obd boost reading is 1.53bar but i would expect real boost to be 1.8,i cant see you being any higher than 2 bar mapped or not ,when you have a remap the boost is generally left alone on 335d's

Bear in mind some take into account atmospheric boost pressure on top etc. Yeah us spec will likely run less boost than UK but likely fueling is slightly different on UK cars.

Still it'll be around 32 ish psi.

if it is 32psi that means 2.2 bar,everyone i have spoken to says 1.8,even the place that mapped mine,well i will see when i run it,may take it for a spin tomorrow


odd how when logging it shows mine peaks at 22.2psi (1.53 bar)though,and thats the reading from the map sensor

[jackstrath]

Ok well I was using that tiesto program and my max boost was 3.7 bar , so 2.7 bar + pressure lol but maby there is a glitch in the program , weird but on idol still says just over a bar

[marknjayne]

i just hope its less that 2 bar as i will have to buy another gauge lol

[marknjayne]

Dammit I'm above 2 bar lol (seems I was wrong and more importantly the apps such as torque and dash command are incorrect too as both of those gave me a 1.5 bar reading ,if anyone is interested in the whole package (gauge , pod and top half of the cowl and hose) message me ,would be ideal for 335i , stack gauges are top quality items too (mine is mechanical s more accurate).

I bought a few steering cowls as I thought if I made a mess I would have a backup so may make my self another and buy a 3 bar gauge

Hi marknjayne,

Would you mind showing how/where you took the boost take off under the hood? (I presume it's a mechanical gauge)

Thanks,
Dave

i replaced the boost pipe with a silicone one and fitted a nipple take off bud as in the pics below

got a boost reading today after borrowing a 3 bar gauge (2.5 bar),may sell the pipe if anyone is interested

[jackstrath]

yup thought it would be higher than 2 bar tbh lol

I've got an lcd boost gauge off the Obd system pics you follow.

AJ,
How did you get that fitted.. link to any write up and item would be greatly appreciated...

[Ajs_435d]

It's a liveview touch screen, running torque Obd and plug in via obd2 port.

Liveview watches can be picked up for as little as 10 quid second hand, plug isn't brilliant it only display one value at a time but can display anything, it was temporarily mounted there.
